Scientists often use containers to hold chemicals. A beaker can hold solids or liquids that won’t release gas and are unlikely to splatter if stirred or heated. A test tube is basically a smaller version of a beaker. It can hold small amounts of chemicals. If you’re worried about a substance splattering, an Erlenmeyer flask might be a good tool to use. Erlenmeyer flasks have a triangular shape to minimize splattering and spilling. To be extra safe about spills, you might use a stopper. However, never heat a container with a stopper on it! According to the passage, why is a substance in an Erlenmeyer flask less likely to spill than a substance in a beaker?

A
because Erlenmeyer flasks can never be heated

B
because Erlenmeyer flasks can only hold solid substances

C
because Erlenmeyer flasks hold smaller amounts of substances than beakers

D
because Erlenmeyer flasks have a triangular shape

D) because Erienmeyer flasks have a triangular shape

Explanation:

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
